SPECIFICATION forming part of Letters Patent No. 447,692, dated March 3, 1891. Application filed June 28, 1890. Serial No. 357,142. (No model.

' matter of the present application for a patent is pointed out in the following specification and claim, and illustrated in the accompanying drawings, in which- Figure 1 is an end view of a bracelet cmbodying the invention. Fig. 2 is a' side elevation, some links being broken away to hibit the inner surface of the bracelet. Fig. 3 is a transverse section in the plane was, Fig. 2, on an enlarged scale. Fig. 4: is a face view of the back plate of one'of the rear links.

Fig. 5 is a plan of the inner face of the front plate of one of the rear links. Fig. 6 is alongitudinal section of a rear link. Fig. 7 is a plan of the inner face of the back plate of one of the front links. Fig.8 is a face view of the front plate of one of the front links. Fig. 9

is a longitudinal section of one of the front ,links in the plane .2 2, Fig. 7.

. In the drawings, the letter I designates a bracelet, which is composed of a series of front links A and a series of rear links B, which are connect-edin the manner of lazy-tongsthat is to say, the ends of the front links A and the ends of the rear links B are alternately con nected by pivots a* a of the peculiar construction hereinafter described, while the front links A are pivoted centrally between slipped over the hand and then compressed to hug the arm snugly.

In order to make the bracelet self-adjusting, I subject the links A 1 to the action of springs t, which have a tendency to close up the links.

In the example described in Patent No. l2S,ll7, above named, the pivots a (0 a, used for connecting the front links A with the rear links I are formed by plain rivets,-and in manufacturing the bracelet described in said patent I have met with great difficulties in.

joining the last links of the bracelet by means of these simple rivets, and particularly in detaching the links when it is necessary on account of repairs. I have succeeded in avoiding these diiiicultics and rendering the manufacture of the bracelets practical from an economical point of view by making the piv- .ots (0* a in the form of tubes (1.,(sce Fig. 23,)

each of which is provided with two heads a a and with an internal scrcw-th read. The head a is situated between the back plate a" andthefront plate a of the front link A, while the head a is made to engage a cavity b formed between the back plate Zr" and the front plate Zr" of the rear link I and is made square, oval, or of anyother form which will prevent it from turning round after it is engaged with said cavity Zr. After the cavity b has been brought in engagement with the head a, a screw a is inserted through a hole in the back plate I) of the rear link 1-5 and screwed into the tube a, which is prevented from turning round by the head a so that said screw can be made as tight as may be desirable. 15y using these double-headed tubular pivots and the screws engaging the same in combination with the rear links B and the front links A, which constitute the bracelet, I am enabled to connect and also to disconnect said links without difiiculty.

'Whatlclaim as new, and desire to secure by Letters Patent, is-

In a bracelet, the combination, with the front link A and the rear link B, of a tubular pivot a, extending loosely through an opening in the back plate of the front linlcA, said tubular pivot a being provided witltian internal screw-thread to engage a screw a",

hand in the presence of two subscribing wit.- and with two heads a a the head a being nesses. situated between the front and rear plates of l A [)0 LPN \V. MAGE'RIIAXS. the front link A, while the head a engages a 5 cavity in the rear link B, substantially as de- Witnesses:

scribed.
